Guan Xue-me · Journal of Langfang Teachers College · 2012
Image enhancement is a kind of basic image processing technology,the purpose of which is to process the image,to be applied to specific Visual effects for better,more useful images.Image enhancement technology currently used,according to the different processing space,can be divided into image enhancement method based on frequency domain and spatial domain method for image enhancement.This article is intended primarily for image enhancement method in frequency domain for research,including low-pass,high-pass filtering method and homomorphic filtering method.
